Hi Jerry;
    While the basic block is unchanged from those pictures, I did modify the orientation of the hose nipples and upsized them for 1 1/4" hose when I added the coolant header tank and rerouted the hose runs for a shorter and cleaner installation. I also moved the turbo coolant to the coolant header tank and plugged this inlet as I felt the turbulence caused by a flow return at this point may be somewhat restrictive. Also I believe I must have had a dyslexic moment when I labelled those pics as it is "RTD", not "RDT".
    Another point that I'd like to bring up right now is hose sizes. I often hear the statement that a car is only run on 30% power on average and yet the auto manufactures use a minimum of 1 1/4" hoses for coolant. But in our airplanes builders commonly use much smaller hoses & fittings usually in order to use AN fittings of which I believe AN16 is the largest (correct me if I'm wrong) and is only 3/4". I don't understand this reasoning. I used 1 1/4" hoses up to the "T" where the rads are plumbed in parallel, where I step it down to 2 -1"hoses. Even the "T's" were made with minimum restriction in mind. If we have a higher power demand from the engine (which is always used as a reason not to use EWP's), then why restrict it's coolant flow?

Thanks Todd, I am pretty sure I will follow your example. Could you provide a verbal description of the adaptor block? Thanks, Jerry 
 
Hi Jerry,
 
Here's a link to the archived message Todd sent when he made the adapter.  It's got a description, and several pics.  
 
Meziere also makes two different adapters for the rotary.  See attached.
 
Cheers,
Rusty (saving Todd some typing)
